As you can see in the screenshot I have a server name appears on the Reverse Lookup zone (icb22) whihc had been removed 2 years ago and it's no longer exist physically. Obviously I need to fix that, I tryed to chnage it but its not allowing me because of following warning<br />
<b>The start of authority (SOA) cannot be updated. Node is a CNAME DNS record</b><br />
Note: Other zones are OK and have no problem.<br />
<br />
How can I fix that zone?<br />
